无机焦磷酸酶是开发新型抗菌剂的潜在靶标。焦磷酸酶偶联高通量筛选检测琥珀酰苯甲酸辅酶A(OSB CoA)合成酶抑制剂导致了一系列新的无机焦磷酸酶抑制剂的意外发现。通过先导化合物的优化设计,合成了一系列3-(3-芳基-吡咯烷-1-基)-5-芳基-1,2,4-三嗪衍生物。四环三嗪类似物之一22 h显示出对多种耐药金黄色葡萄球菌菌株的有希望的抗生素活性,以及对结核分枝杆菌和炭疽杆菌的活性,其浓度对哺乳动物细胞无细胞毒性。
Inorganic pyrophosphatases are potential targets for the development of novel antibacterial agents. A pyrophosphatase-coupled high-throughput screening assay intended to detecto-succinyl benzoic acid coenzyme A (OSB CoA) synthetase inhibitors led to the unexpected discovery of a new series of novel inorganic pyrophosphatase inhibitors. Lead optimization studies resulted in a series of 3-(3-aryl-pyrrolidin-1-yl)-5-aryl-1,2,4-triazine derivatives that were prepared by an efficient synthetic pathway. One of the tetracyclic triazine analogues22hdisplayed promising antibiotic activity against a wide variety of drug-resistantStaphylococcus aureusstrains, as well as activity versusMycobacterium tuberculosisandBacillus anthracis, at a concentration that was not cytotoxic to mammalian cells.
